Rumor has it that this German person named 'Norbert' made this rig under 50 euros (ha!). Not only did he make all the servomotor associated shifting mechanism himself, he also built the aero bike from bottom up including the wheels.

Pay close attention to this servo setup. Here are the pics, obtained from WW Forum. Credits to you guys out there.

What looks to be an 8 speed Dura Ace rear derailleur combined with a servomotor!

I wonder if he removed the springs from the derailleurs & just used the servos to move them both ways. From my limited experience with RC planes when I was young I don't remember servos in that size having that much torque. Especially at rest I'd imagine the springs could overcome the friction in the servo.
